Each claim group has one outcome, the most severe any of its answers had: contradict, site_conflict, stale, not_on_site, match, then unjudged. A dismissed contradiction or site conflict counts as dismissed. ## OpenAPI ````yaml /openapi.json get /projects/{projectId}/accuracy openapi: 3.1.0 info: title: DevTune API version: 2.0.0 description: >- API for programmatic access to your AI visibility data, webhook subscriptions, and automation workflows.
